Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the engine.
Disconnect the battery to prevent any electrical issues.

2. Brake Inspection and Replacement

Remove Wheel Assembly
- Use a lug wrench to loosen and remove the lug nuts.
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheel.
Inspect Brake Components
- Examine brake pads for thickness; replace if worn down to 3mm or less.
- Inspect brake rotors for scoring or warping; replace if damaged.
- Check caliper functionality and look for leaks.
Replace Brake Pads and Rotors
- If necessary, remove caliper bolts with a socket wrench and slide the caliper off.
- Remove old brake pads and install new ones. Use brake grease on the backing of the pads.
- Replace the rotor if damaged and reassemble the caliper.

3. Wheel Bearing Inspection and Replacement

Check Wheel Bearings
- Spin the wheel by hand; listen for grinding noises.
- If noise is present, remove the wheel hub assembly as needed.
Replace Wheel Bearings
- Use a bearing puller to remove the old bearings from the hub.
- Press in new bearings with a bearing press.
- Reassemble the wheel hub and reinstall the wheel.

4. CV Joint and Driveshaft Inspection

Inspect CV Joint
- Inspect the rubber boots for tears or leaks.
- Remove the axle nut and pull the axle to check the CV joint for wear.
Replace CV Joint or Axle
- If necessary, replace the CV joint/axle assembly.
- Reinstall and torque the axle nut to manufacturer specifications (typically around 150 ft-lbs).
